Answer (1)
Explanation about the answers:1. "Hypothesis" because it's a key step in scientific method.2. "Cell" Because Cells are the fundamental building blocks of all living organs.3. "Chemical Energy" Food contains Chemical Energy stored in the bonds of molecules.4. "Mars" Mars is known as a Red Planet due to its reddish appearance.5. "Photosynthesis" Photosynthesis is the process by which plants and some algue use sunlight, water, and carbon dioxide to produce they're own food (glucose).6. "Crude oil" •—• (I don't how to explain this one, sor).7. "To reduce error in measurements" Multiple trials help to minimize the impact of random errors and variations in measurements.8. "Energy cannot be created nor destroyed" This is the law of conservation of energy, a fundamental principle in physics. Energy can be transformed from one form to another.9. "A boy picking up a feather" Work is done when a force causes an object to move a distance. In this case, the boy applies a force to lift the feather, causing it to move.10. "Elevator" Elevators move vertically and do not use an inclined plane.Remember, when a teacher gave you an Activity about the lesson. Do it by yourself.
